The AirTAC GR20006LC1TK AirTAC Low-Pressure Regulator, NPT1/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT1/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR20006LC1TK is an AirTAC GR200 series air pressure regulator, built purely for pressure regulation - it contains no filter, no bowl and no lubricator. This unit is the low-pressure type (code L), so it regulates downstream pressure up to 0.4 MPa, and it is fitted with an external round pressure gauge scaled in MPa (code C1) so the set pressure can be read directly at the unit. The check valve (code K) holds the downstream setting if upstream supply is lost. The 06 port code gives a 1/8 inch NPT thread, and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 inch to 1 inch, in standard or low-pressure types, with embedded square or external round gauges in MPa, psi or bar scales, an optional reverse/check valve, and PT (standard), G or NPT threads to order. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GR200 | G-series pressure regulator, 200 body — sets the port range. |
|---|---|
| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |
| (blank) | Fixing bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom rather than from a single rated figure.

A machining cell uses air clamps that must not crush thin-walled aluminium parts. This low-pressure GR200 regulator holds the clamp circuit at a gentle set pressure, with the round MPa gauge letting the setter read and lock the value at the unit.
A plant air header at full line pressure feeds positioner and pilot circuits on control valves that need a much lower, stable supply. This regulator steps the pressure down in a compact 1/8 inch NPT footprint, and the check valve keeps the pilot line charged through brief supply dips.
A laboratory test bench runs small air cylinders and jigs at reduced pressure well below the shop supply. The low-pressure GR20006LC1TK gives the bench its own regulated supply with a clear MPa readout, and the included bracket lets it be panel-mounted at the station.
Start with the port step: GR200 is the smaller end of the GR range (ports 1/8 to 1/4 inch across the family), so match the size to the air demand of the circuit rather than just the existing pipe thread. Because this is the low-pressure type (L), choose it where the working pressure must stay at or below 0.4 MPa; for higher set points use the standard GR type. This unit carries the K check-valve option, which is worth specifying whenever a lost supply must not dump the downstream setting. Gauge options are the embedded square gauge or the external round gauge fitted here, in MPa, psi or bar scale. Thread is NPT on this code; PT is the catalogue standard and G is also available to order. A mounting bracket is included, and GR is also panel-mountable. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR regulator flow as curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote. Tell us your application and we will confirm the relevant flow figures from the datasheet on request before you order.
The L in the code marks the low-pressure version of the GR series: it regulates downstream pressure up to 0.4 MPa, whereas the standard type covers the full GR range up to 0.9 MPa. Inlet pressure is still up to 1.0 MPa (145 psi), and the operating temperature range for GR is -20 to 70 C.
